Background

Serpin A9 (Serine proteinase inhibitor-clade A #9; also GCET1, Centerin and Serpin A11) is a 46 kDa, secreted member of the alpha 1-antitrypsin (clade A) subfamily, serpin superfamily of protease inhibitors. It is only produced by normal and lymphoma germinal center B cells. Its function is unknown, but it presumably acts as an inhibitor of a trypsin-like protease. Mature human Serpin A9 is presumably 394 amino acids (aa) in length. It contains one Serpin motif (aa 405-415). There are multiple splice variants associated with Serpin A9. There are alternate start sites at Met19, Met99 and Met150. A fourth isoform shows a two aa substitution for aa 369-435, while a fifth isoform shares this same substitution coupled with a 39 aa substitution for aa 1-75. A sixth variant shows a deletion of aa 91-190. Mature human Serpin A9 shares 67% aa identity with mouse Serpin A9.
